INKSTAND.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed April 20, 1906. Serial No. 312,752.

To @ZZ whom it may concern.-

Be it known that I, FRANK M. ASHLEY, a citizen of the United States, anda resident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Inkstands, ofwhich the following is a specification.

My invention relates to inkstands of the automatic type and the objectof the invention is to provide an inkstand of this type which is verysimple in construction and in whichA the parts are more easy to make.

The particular features of novelty will be pointed out in the claimshereinafter, and described in the following specification.

Figure l, is a vertical sectional view of one form of my improvedinkstand and Fig. 2, is a second form thereof, also shown in verticalsection. Fig. 3, is an inverted view of the cap piece.

In Fig. 1, I show the inkstand made with a iioat which extends above thetop of the body portion and in this type it is necessary when making astand of considerable depth and capacity, to adjust the height of thefloat in the reservoir to prevent the oat from standing too high in thestand'when the reservoir is fullv of ink.

In Fig. 2, I show the float with the top of the dip tube located belowthe top ofy the stand, and in this case I do not need to adjust the'height of the float in the stand since the same cannot float above thetop of the stand due to the restraining cap piece.

The feature common to both styles is the form of the lower end of thefloat and the lower end of the reservoir in which the iioat is moved inoperating the stand. Heretofore in making these types of stands, thelower or auxiliary reservoir has been made with the side walls thereofapproximately parallel to each other or practically cylindrical in form,and this form has been hard to make in pressed glass, which is what moststands of this type are made from, due to the trouble in withdrawing theplunger from the glass when the glass is in a molten condition, withoutdestroying the shape of the lower reservoir. I have therefore made thelower reservoir of conical form, which allows the plunger to withdraweasily from the glass in the pressing operation, thus allowing morebases to be made in a given time and reducing the number of bad baseswhich have to be thrown out since they cannot be used if not properlyformed, and therefore the cost of the bases have been correspondinglyreduced. By making the lower end of the fioat also with tapering sidesto approximately correspond to the taper of the walls ofthe lowerreservoir, I accomplish a very useful and decided advantage over allconstructions of inkstands of this type heretofore made.

Referring to the drawings, A indicates the base ,or body portion havingtherein a reservoir B, the lower end of which is tapered to allow theplunger to easily withdraw therefrom in pressing, and also serves toassist in bringing up the ink in a proper manner to the dip cup of thefloat, when the float is depressed therein.`

Referring to Fig. 1, the float C is made in two parts, the dip tube Cbeing made separate from the large cylindrical` part on which it ismounted, and being connected thereto` by a friction joint at c. Thelower end of the cylindrical part, indicated by C2 is tapered so thatwhen the iioat is depressed to the bottom of the reservoir, the walls ofthe float and reservoir will almost touch each other, but are preventedfrom touching by the extension of the lower end of the dip tube, whichcontacts with the bottom of the reservoir when the float is in itslowest position, and thus prevents the float from wedging in thereservoir. The top of the stand A is turned inward to act as a guide forthe movement of the float. The reservoir above the tapered portion maybe extended laterally to add ink capacity if desired.

Referring to Fig. 2, the joint c is located lower on the float as shown,and aseparate cap piece Dis located on the top of the reservoir, and isprovided with a guide-way D/ in which. is located grooves d-d-d-d formed-by projections e-e-c--c which serve as the.

guides for the upper end of the float, the grooves serving to allow theair to escape from the reservoir during the movement of the float, andalso serving to allow any overflow of ink from the dip cup, to flow backinto the reservoir, should such an accident occur. j

When the float is in its normal floating position, an annular passage isformed between the outer surface of the lower end of the float and theinner surface of the lower end of the reservoir, and as the fioat isdepressed, this passage is correspondingly restricted.

ITO

Making the float in. two parts serves to allow the parts to be moreeasily manufactured and in Fig. l, the hei ht of the fioat in thereservoiris governed y removing the dip tube C from the large cylinderwhen the 'stand is filled, thus allowing the air in the float to escapewhile the float is being inserted in the reservoir, thus allowing theink to flow upward in the float to the same height that it stands in theouter reservoir, when the dip tube is inserted in the cylinder, and bylifting the cylinder a short distance, a portion of the ink will flowout of the float into the reservoir, and air will be drawn in the floatin place thereof, and the float will then stand at a proper height tobring up the ink to the dip cup when depressed.

In Fig.'2, I do not need to adjust the float, since it will always floatupward so long as there is sufficient ink in the stand to buoy the same.

In fillinfT the stand shown in Fig. 2, the cap-piece is removed and thefloat also removed, and ink is poured into the reservoir until the sameis about half lled, then the l float is inserted, 'the air being trappedin the bell thereof, and the cap piece D replaced, the ink being forcedupward in the reservoir and nearly filling the stand due to thedisplacement of the float.

v In operation, the float on being depressed will move downward and thepassage between the float and the wall of the reservoir will berestricted gradually, and the ink forced upward from the bottom of thereservoir to the dip cup. This movement and the gradual contraction ofthe passage serves to prevent the ink from spurting when the cup isdepressed since the ink is not trapped so quickly as has heretofore beenthe custom,

and a part of the ink is free to iiow from the lower end of thereservoir to the upper part thereof when the fioat first begins to move,as will be easily understood. The lower end ofthe di tube may becontracted as shown at F if cesired, to further prevent the ink fromspurting when the float is very quickly depressed, which is the onlytime that any excess of ink or spurting, is likely to occur.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. An inkstand having a reservoir with an extended tapering wall, and afloat vertically movable therein and co-operative therewith to force inkto the upper end thereof as described. .f

2. An inkstand havinga reservoir with tapering wall, a float movabletherein and forming a passage between said wall and float, therebygradually restricting said passage by the movement of the float for thepurpose set forth.

3. An inkstand having a reservoir with a tapering wall, and a floathaving a tapering wall, the downward movement of said float. serving ,tolessen the distance between said walls and to upwardly force ink fromsaid reservoir. A

4. An inkstand having a reservoir with a tapering wall, a floatvertically movable therein and co-operating with said wall to force inkupward therefrom, and means for restricting the upward movement of thefloat.
